Subject: [PATCH] ath9k: release allocated buffer if timed out
Date: Fri,  6 Sep 2019 13:59:30 -0500	[thread overview]
Message-ID: <20190906185931.19288-1-navid.emamdoost@gmail.com> (raw)

In ath9k_wmi_cmd, the allocated network buffer needs to be released
if timeout happens. Otherwise memory will be leaked.
